Hi Angelina,
I'm happy that you were persistant and finally got the treatment you need. I'm sure you already know you have to be your own advocate. I am 29 and have never smoked so nobody thought my "sore" would be cancer either. I hope you are healing and feeling better from your surgeries. Hopefully they will give you some good information at your next appointment on the 20th.
Keep looking for doctors until you find one you click with. It can be hard, I know. I agree with Cecilia, make a list of your questions and bring someone with you. I either take, my husband, mom or sister. They are all awesome. Also, have your husband look at your tongue and look for any changes. My husband checks my tongue all the time and he knows when it looks good or not. It give me much peace of mind.
Sorry be long winded!! Let us know how your appointment goes!!
